WebThe British thermal unit (BTU or Btu) is a measure of heat, which is measured in units of energy.It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.It is also part of the United States customary units. The modern SI unit for energy is the joule (J); one BTU equals about 1,055 J (varying within … WebBTU/Hour Square Foot : The BTU per hour per square foot is a unit of heat flux density which is a US Customary and British Imperial units. Its symbol is BTU/h•ft². Watt/Square Meter : The watt per square meter is a derived unit of heat flux density in the International System of Units SI. Its symbol is W/m². One watt per square meter is equal to 1J/s•m².
